Macro shadow_clone::shadow_clone

macro_rules! shadow_clone {
    ($ ($to_clone:ident) ,*) => { ... };
}

Use this macro to clone variables into the current scope shadowing old ones.

Examples

let s = "foo".to_string();
let c = move |x: i32| format!("{}{}", s, x);
let bar = s;

This will not compile as s has been moved into the closure.

This issue can be solved with this macro.

use shadow_clone::shadow_clone;
let s = "foo".to_string();
{
    shadow_clone!(s);
    let c = move |x: i32| format!("{}{}", s, x);
}
let bar = s;

You can also clone multiple variables separated by commas. shadow_clone!(foo, bar);
